GENERAL SAFETY INFORMATIONENOM00009-0

SAFE OPERATION OF BOATAs the operator/driver of the boat, you are responsible for the safety of those aboard and

those in other boat around yours, and for following local boating regulations. You shouldbe thoroughly knowledgeable on how to correctly operate the boat, outboard motor, andaccessories. To learn about the correct operation and maintenance of the outboard motor,please read through this manual carefully.It is very difficult for a person standing or floating in the water to take evasive action shouldhe or she see a power boat heading in his/her direction, even at a slow speed. Therefore,when your boat is in the immediate vicinity of people in the water, the outboard motorshould be shifted to neutral and shut off.ENOW00005-0

SERIOUS INJURY IS LIKELY IF A PERSON IN THE WATER MAKES CONTACT WITH A MOV-ING BOAT, GEAR HOUSING, PROPELLER, OR ANY SOLID DEVICE RIGIDLY ATTACHED TO

A BOAT OR GEAR HOUSING.

ENOM0008-A

EMERGENCY STOP SWITCHThe Emergency Stop Switch will stall the outboard motor when the stop switch lanyard is

pulled off. This stop switch lanyard has to be attached to the operator of the outboardmotor to minimize or prevent injuries from the propeller in case the operator falls over-board.It is operators responsibility to use the Emergency Stop Switch Lanyard.ENOW00004-A

Accidental activation of the Emergency Stop Switch (such as the tether being pulled out inheavy seas) could cause passengers to lose their balance and even fall overboard, or it

could result in loss of power in heavy seas, strong currents, or high winds. Loss of controlwhile mooring is another potential hazard.To minimize accidental activation of the Emergency Stop Switch, the 500 mm (20 inch.) stopswitch lanyard is coiled and can extended to a full 1300 mm (51 inch.).

ENOM00800-A

PERSONAL FLOATATION DEVICEAs the operator/driver and passenger of the boat, you are responsible to wear a PFD (Per-sonal Floatation Device) while on the boat.

Before beginning the running test, checkthat the boat with maximum capacityloading floats on the water in a properattitude. Check the position of watersurface on the driveshaft housing. If thewater surface is near the bottom cowl-ing, in high waves, water may enter theengine cylinders.

Incorrect outboard motor mountingheight or existence of underwaterobject(s), such as hull bottom design,bottom surface conditions or underwa-ter accessories, can cause water spraypossibly reaching the engine through anopening of the bottom cowling duringcruising. Exposing the engine to suchconditions for extended periods canlead to severe engine damage.

Mounting the outboard motor without

following this manual can lead to unsafeconditions such as poor maneuverabil-ity, lack of control or fire.

Loose clamp screws and/or mountingbolts can lead to the release or displace-ment of the outboard motor, possiblyresulting in lost of control and/or seriouspersonal injury. Be sure that fastenersare tightened to the specified torque (30Nm (3.0 kgf) 13 ft-lb). Check the fasten-

ers for tightness from time to time. Be sure to use outboard mounting fas-

teners included in the outboard motorpackage or their equivalents in terms ofsize, material, quality and strength.Tighten fasteners to the specified torque(30 Nm (3.0 kgf) 13 ft-lb). Test cruise tocheck i f fasteners are t ightenedsecurely.

Outboard motor mounting must be per-formed by trained service person(s)using lift or hoist with sufficient capacity.

lines Starting and operating difficulties

If the use of gasoline containing alcohol isinevitable, or presence of alcohol is sus-pected in the gasoline, it is recommendedto add a filter that has water separatingcapability, and check the fuel system forleaks and mechanical parts for corrosionand abnormal wear more frequently.And, in case any of such abnormality is

found, discontinue the use of such gaso-line and contact our dealer immediately.If the outboard motor will only be usedinfrequently, please see the remarks onfuel deterioration in the STORAGE chapter(P 78) for additional information.

ENOW00020-0

When operating a TOHATSU engine ongasoline containing alcohol, storage ofgasoline in the fuel tank for long periodsshould be avoided. Long periods of stor-age, common to boats, create unique prob-lems. In cars, alcohol blend fuels normallyare consumed before they can absorbenough moisture to cause trouble, butboats often sit idle long enough for phaseseparation to take place. In addition, inter-

nal corrosion may take place during stor-

age if alcohol has washed protective oilfilms from internal components.
